Decides whether a given object is a probability space.

1 | ```
is.probspace(x)
``` |

`x` |
an object for which probability space status should be checked. |

It first checks if the class of the object includes `ps`

, and if so `TRUE`

is returned. If not, then it checks that the object is a data frame and contains a `probs`

column. Lastly, it checks whether all entries of `probs`

are nonnegative. Note that it does not check whether the sum of `probs`

is one, to allow for the possibility that the input object is a proper subset of a probability space.

Logical.
